Mosseri has made combatting online bullying a top priority since he took over the reigns for Instagram in October.

Instagram on Monday announced the launch of a new AI feature that will notify users when a comment they write could be considered offensive before they post it. Instagram said it will also soon begin testing a new feature called “Restrict” that will allow users to hide comments from specific users without notifying those users that they’ve been muted.

Mosseri has stressed this at all-hands meetings and in an emails to his employees, current and former Instagram employees told CNBC in May. Mosseri also announced in April that Instagram would begin experimenting with hiding like counts as a way to make the social network “a less pressurized environment.”
